Actually, a number of analysis over the years have shown that you need to limit non-isolatable nodes in a system to a maximum of six, there is also a substantial body of evidence that N+1 redundancy only adds redundancy for less than 6 units total. It would seem their analysis also relies on the ability to limit the number of nodes post-repair.
The idea may not be new, but the expression is interesting.
